LED bulbs could work as a wireless router and connect you to the internet! Dr. Maite Brandt-Pearce, an engineering professor at the University of Virginia and her team unveiled a novel way to transmit wireless data in light waves from LED lights a much more reliable and faster alternative to radio wave Wi-Fi.
They developed a modulation algorithm that increases the throughput of data in visible light communications and more data can be transmitted without using any additional energy. As more light fixtures get replaced with LED lights, one could have different access points to the same network. The technology would require no more energy than is currently used to emit light. The light waves can carry data at 300 megabits per second from LED fixtures to wireless devices.
